Not enough iodine in the diet can cause mental retardation and stunted growth in children and an enlarged thyroid gland goitre in adults. Good sources of iodine include bread fortified with iodised salt and any type of seafood, including seaweed. Iodine is found in a range of foods including dairy products, seafood, seaweed kelp , eggs, bread, some vegetables and iodised salt.
Our bodies need iodine for the development of essential thyroid hormones. The thyroid is a gland in the throat that regulates many metabolic processes, such as growth and energy use. All women who are pregnant, breastfeeding or considering becoming pregnant should ask their health professional for advice about their individual dietary needs. This overgrowth of the thyroid gland is called goitre. If the deficiency is long term, hypothyroidism develops. This is a condition in which not enough thyroid hormone is produced.
Symptoms include dry skin, hair loss, fatigue and slowed reflexes. Iodine deficiency in babies and children In the developing fetus, baby or young child, the effects of iodine deficiency are serious. They include stunted growth, diminished intelligence and retardation. Lack of iodine is a major problem in developing countries. There is evidence that some levels of iodine deficiency may be too mild to cause goitre, but may still retard brain development. In Australia, studies conducted over the last decade in Victoria and New South Wales indicate the presence of mild-to-moderate iodine deficiency in all groups tested.
Western Australia and Queensland appear to have adequate intakes, while South Australia is borderline. Iodine fortification of bread Since October , iodised salt has replaced non-iodised salt in all bread sold in Australia except organic bread.
This is in line with the Food Standards Australia New Zealand FSANZ mandatory iodine fortification regulation, introduced to help address the re-emergence of iodine deficiency across most of the population.
International guidance and experience have shown that using iodised salt is one of the best ways to reduce iodine deficiency, and adding it to bread is the easiest way to add extra iodine to the food supply. Information on the effectiveness of mandatory fortification is yet to be released, but there is some evidence that it has improved the iodine status of some groups. Bread fortified with iodised salt can provide enough iodine to avoid low thyroid activity for most people, without the need to add iodised salt to their diet.
Salt contributes to hypertension high blood pressure and there are efforts globally to encourage people to eat less salt by avoiding adding salt in cooking and at the table. Recommended daily intake of iodine The recommended daily intake RDI for iodine depends on your age and life stage.
The amount we need is very small around one teaspoonful over a lifetime for most adults when compared to other nutrients. Iodine intake in Australia has dropped In the past, low dietary levels of iodine were thought to be a problem only in developing countries. However, some researchers suspect that iodine intake levels in Australia have dropped considerably, perhaps by as much as half, over the past few decades.
Ongoing research is looking at the problem and what might be done about it. Some reasons for low iodine intake may include: How to get enough iodine in your diet The best way to get the nutrients your body needs is as part of a healthy, well-balanced diet. The Australian Guide to Healthy Eating provides advice on recommended amounts of food from each of the five food groups. Eating according to this guide provides sufficient iodine for most people.
Some suggestions to make sure you get the required daily amount of iodine include: Enjoy a wide variety of nutritious foods from the five food groups. Seafood — dietitians recommend two to three meals of seafood per week to get the beneficial fish oils. Eating fish twice a week will also provide most adults with enough iodine to fulfil their average iodine requirement.
Bread is now made using iodised salt in Australia — you should still select wholegrain and high-fibre varieties. Seaweed, dairy products and eggs provide additional dietary sources of iodine. Some vegetables — may contain iodine, but only if they are grown in iodine-rich soils.
Supplements — may be necessary if your dietary intake is inadequate. Although it comes from the ocean, sea salt is not a good source of iodine. Iodine and pregnancy Pregnant women need higher levels of iodine, as lack of this nutrient can retard normal development in a baby. In Australia, the National Health and Medical Research Council NHMRC recommends that all women who are pregnant, breastfeeding or considering pregnancy take an iodine supplement of mcg each day to make sure their needs are met.
If you are pregnant, breastfeeding or considering becoming pregnant, ask your doctor for advice about your individual daily needs. In particular, women with pre-existing thyroid conditions should not take iodine supplements until they have checked with their doctor. Seafood is a valuable source of iodine, but pregnant women, or women intending to become pregnant within the next six months, should take care to avoid seafood that may contain large amounts of mercury.
Mercury can be passed through the placenta and may affect the brain development of your baby. Some fish that contain high levels of mercury include shark, orange roughy, swordfish and ling. Vegetarian diet Vegetarians can help make sure they get enough iodine by including bread, seaweed and some soymilks that include extracts of seaweed as part of a healthy diet, consistent with the Australian Guide to Healthy Eating.

And, of course, most of the sea vegetables beat out all of the animal products by a very wide margin. In my estimation, one can get far more and better quality iodine from whole foods than from animals. The importance of iodine in one's diet can not be overstated. There is a widespread belief that iodine is only needed by the thyroid gland, when in fact the entire body requires iodine for optimal functioning. In addition, according to family practitioner and iodine specialist, Dr. Jorge Flechas, MD, thyroid hormones are also created in the white blood cells of our bone marrow and in women's ovaries.
Flechas also contends that iodine is required by our cerebral spinal fluid, salivary glands, pancreas, breasts, stomach, brain, muscles, skin and thymus. An iodine deficiency in any of these organs and tissues can cause problems. In the muscles, a deficiency may cause fibromyalgia, pain, fibrosis, nodules and scar tissue. The salivary glands may become unable to produce saliva and lead to dry mouth.
Dry skin and an inability to sweat are also acute signs of iodine deficiency. Reduced alertness and lowered IQ is how iodine deficiency affects the brain; in gestating fetuses and young children, a deficiency can have life long repercussions.
Iodine has also been shown to help prevent cancer, by helping the body properly program cells to go into apoptosis PCD — programmed cell death when they mutate, thus preventing the proliferation of cancer.
David Brownstein, MD, a family physician and holistic medicine practitioner, has written on this topic in regards to breast cancer, in his newsletter Natural Way to Health. You've probably heard about the relationship between iodine and your thyroid. You were probably told to use iodized salt to protect your thyroid. But what doctor ever told you about iodine and breast cancer? In fact, there is a long history in the medical literature of treating and preventing breast diseases with iodine.
Your breasts contain one of the highest concentrations of iodine in your body. And when it comes to your breasts, iodine deficiency is associated with cyst formation. Many women develop fibrocystic breast disease, with cysts turning into small lumps called nodules.
In prolonged iodine deficiency, these nodules become hyperplastic, meaning that an enlargement has formed due to an abnormal multiplication of cells. Hyperplasticity is a precursor to cancer. Thus, long-term iodine deficiency can lead to breast cancer. But here's the good news: Iodine therapy can kill cancer cells! And you can't just load up on more iodized salt or any old brand of iodine and expect to see a benefit. The recommended daily allowance RDA of iodine in the USA is only mcg per day for adults, mcg during pregnancy and mcg while breast feeding, which are all considered minimum levels.
And compared to a nation like Japan, which has significantly lower prostate, breast, endometrial and ovarian cancer rates, and where the average daily iodine intake from food sources is approximately RDA , one cannot help but recognize that the U. RDA for iodine is rather minuscule.
